Understanding chronic ankle instability and how it affects your daily movement.

Understanding Chronic Ankle Instability

Chronic ankle instability is a condition characterized by a recurring giving way of the outer (lateral) side of the ankle. This condition often develops after repeated ankle sprains. Usually, the giving way occurs while walking or doing other activities, but it can also happen when you are just standing. Many athletes, as well as others, suffer from chronic ankle instability.

The ligaments in your ankle ensure stability by restraining side-to-side movement. When you sprain your ankle, the connective tissues (ligaments) are stretched or torn, and the ability to balance and stabilize is often affected. Each subsequent sprain further weakens the ligaments, leading to greater instability and additional problems in the ankle.

People with chronic ankle instability often report repeated turning of the ankle on uneven surfaces or during sports, persistent discomfort and swelling, pain or tenderness, and a wobbly or unstable feeling. Risk factors include a prior ankle sprain, returning to sports too soon, obesity, and skipping follow-up strengthening exercises.

To evaluate your condition, the foot and ankle surgeon will ask about previous ankle injuries and examine your ankle for tender areas, swelling, and instability. X-rays or other imaging studies such as ultrasound or MRI may help further evaluate the ankle. If you suffer from chronic ankle instability or ongoing ankle pain, do not hesitate to call us or request an appointment online so we can set you on the best path for recovery.

Treatment Options and the InternalBrace

Treatment for chronic ankle instability is based on the results of your examination and tests, as well as your level of activity. Nonsurgical care often includes physical therapy to strengthen the ankle, improve balance and range of motion, and retrain your muscles. Some patients wear an ankle brace for support and to keep the ankle from turning, and nonsteroidal anti-inflammatory drugs such as ibuprofen may be prescribed to reduce pain and inflammation.

When conservative care does not resolve the problem, surgery may be recommended. Surgery usually involves repair or reconstruction of the damaged ligaments, selected based on the severity of the instability and your activity level. One advanced option is the InternalBrace procedure, a minimally invasive technique that reinforces the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL), the primary stabilizers of the ankle.

Unlike traditional ligament repair, the InternalBrace uses high-strength suture tape to provide immediate support while allowing natural healing. It is typically performed as an outpatient procedure under local or general anesthesia, takes less than an hour, and most patients go home the same day. You may be a good candidate if you have frequent sprains or have tried bracing and physical therapy without success.

Recovery is generally faster than traditional ligament repair. The first two weeks involve limited weight-bearing with crutches and a protective boot, weeks three through six focus on gradual weight-bearing and therapy, and weeks six through twelve bring a progressive return to normal activities. Following your podiatrist’s rehabilitation plan ensures the best long-term outcome.
